Materials

Leaded (Tin) Bronze SAE660 / C93200

SAE660 or C93200 is a Leaded (Tin) continuously cast bronze and is a standard in the industry for light/medium bearing applications. Leaded (Tin) Bronze SAE660 or C93200 is suitable for various applications under medium loads. Leaded (Tin) Bronze SAE660 / C93200 has good resistance to seawater and brine enabling it to be used in the valve and pump industry.

Phosphor Bronze PB1

PB1 is a cast material containing 10-11.5% tin and small amounts of phosphorus. Phosphor Bronze PB1 has high mechanical strength and has good conductivity and wear resistance . Also, with excellent corrosion and fatigue resistance. Phosphor Bronze PB1 can be soldered and brazed.

Aluminium Bronze BS2874 CA104

CA104 is wrought high strength aluminium bronze, the commonly most used bronze in the market in the UK.

Aluminium Bronze BS2874 CA104 is used for its high strength and excellent corrosion resistance to sea water and other aggressive environments. Aluminium Bronze BS2874 CA104 also has good wear and abrasive resistance the ability to withstand shock loading.

Aluminium Bronze NES833 DEF-STAN 02-833

Aluminium Bronze NES833 DEF-STAN 02-833 is a nickel aluminium bronze similar to CA104 but manufactured to the requirements of the Ministry of Defence. The MOD stipulate a nickel content that exceeds the iron content to improve the general corrosion performance.

Aluminium Bronze C63000

One of the American grades of nickel aluminium bronze. Aluminium bronze C63000 contains around 10% aluminium, 5% nickel and 3% iron the alloy offers an inherent high strength and hardness combined with a very good toughness and an excellent resistance to wear, shock and abrasion.

Aluminium Bronze C63200

Aluminium bronze C63200 is a strong, corrosion resistant material that performs well at high and low temperatures. It also has a low magnetic permeability, making it ideal for use on instrumentation systems, seawater piping systems and marine propulsion units.
